HBASE-20100 TestEnableTableProcedure flakey 

Allow OPEN as a possible state when update region transition state.
Usually state is OPENING but if crash before finish step is completed,
on replay, master may have read that the state is OPEN from meta table
and so will think it open... When we replay the procedure finish, allow
that the region is already OPEN.
